The **D413-R1LA-G2** is a specific model of a **Miniature Snap Action Switch** (commonly known as a Microswitch), typically manufactured by **Cherry (ZF Electronics)**. These components are used to detect physical motion or to act as a limit switch in various industrial and consumer devices. --- ### Technical Specifications The model number identifies specific electrical and physical characteristics. Below is a breakdown of the typical specifications for this series: | Feature | Specification | | :--- | :--- | | **Switch Type** | Snap Action / Microswitch | | **Circuitry** | SPDT (Single Pole Double Throw) | | **Current Rating** | 0.1A to 10A (Depending on specific load type) | | **Voltage Rating** | 250V AC | | **Actuator Style** | Standard Lever (Roller or Straight based on suffix) | | **Terminal Type** | Solder Terminals / Quick Connect | | **Operating Force** | Approximately 45g to 150g | --- ### Component Breakdown #### 1. Internal Mechanism The "Snap Action" means the switch uses a spring-loaded mechanism to flip the contacts almost instantaneously when a specific trip point is reached. This minimizes arcing and ensures a reliable electrical connection regardless of the speed of the physical actuation. #### 2. Electrical Contacts * **Common (COM):** The input terminal. * **Normally Open (NO):** The circuit is open until the lever is pressed. * **Normally Closed (NC):** The circuit is closed until the lever is pressed. #### 3. Housing and Durability * **Material:** Usually high-grade thermoplastic (PET or PBT) for heat resistance. * **Life Expectancy:** Mechanical life is typically rated for 1 million cycles or more. --- ### Key Applications Due to its precision and reliability, the D413 series is found in: * **Home Appliances:** Door interlocks for microwaves or washing machines. * **Industrial:** Limit switches on CNC machines or 3D printers. * **Automotive:** Gear shifters or seat adjustment sensors. * **Vending Machines:** Detecting the passage of a coin or product. --- ### Nomenclature Breakdown (Typical for D4 Series) * **D4:** Series designation (Standard Miniature). * **1:** Standard Operating Force. * **3:** Solder Terminals. * **R1:** Indicates a specific lever type (likely a simulated roller or short lever). * **LA:** Contact material/rating code. * **G2:** Packaging or minor variation code.
